Simulation research on collector plate structure of solar air collector

This paper adopts the method of Fluent software simulation and simulates research the thermal performance of a solar air collector´s with porous and fold lined. Changes in the structure of the collector plates whether the openings, folded plate and the plate hole collector aspects to impact performance are discussed. In order to have comparable, to simulate in the intensity of solar radiation, wind speed and imported air supply means, collector plates and glass cover settings such as radiation carried out under identical conditions. By simulating the temperature distribution, flow distribution of the collector and the internal air, it can be obtain the conclusions: in the collector plates to keep the same shape, hole board than non-hole plate uneven temperature distribution significantly, and local overheating, non-hole lead was the heat collector plate collector thermal efficiency with the collector plate lower than the hole; the hole in the collector plate to keep the same rate, opening flat and folded plate openings due to air within the collector differences in flow pattern on the plate led to overheating, increasing the external environment, heat loss, solar collector performance decreases.
